Study of the effect of organic and mineral fertilization techniques on the stability of soil aggregates treated with different concentrations of sodium chloride salt


Abstract in English

A laboratory experiment was carried out in the Clay Minerals and Colloids Laboratory in the Department of Soil Sciences and Land Reclamation at the Faculty of Agricultural Engineering - University of Aleppo. The research aims to know the effect of sodium chloride salt (NaCl) on the stability of artificial soil complexes and to know the salt concentration that causes the greatest damage in the destruction of artificial soil aggregates at four concentrations (0-2-4-6) g.𝓁-1 , This study also aimed to find solutions to the problem of irrigation with salty water and the deterioration of soil structure through the use of organic fertilization techniques (potassium humate) and mineral fertilization (Gypsium) at two concentrations (1-2)% of the weight of the soil. The results indicated the effect of the increasing concentration of sodium chloride salt in increasing the percentage of soil complexes that were destroyed. The results of the study also indicated that soil aggregates were more damaged by sodium chloride salt at a concentration of (6) g.𝓁-1, where the percentage of destroyed aggregates reached about (33.71) %. The results also indicated the role of organic and mineral fertilization techniques in increasing the stability of soil aggregates against the destructive action of sodium ions. The results of the statistical analysis showed the superiority of organic fertilization technology in its two levels over mineral fertilization in increasing the stability of soil complexes.
